How to play this (so cliché) hand in a profitable way?

As I see it the only reason to call flop/turn is to hit a marginal top pair or to maybe bluff a scary ace. Don't ok now if you have any stats or reads on villain but when he fires second you should believe he has something and youre not Gina beat him with K high. I would fold turn. As played I would have bet half pot otr

I also don't see any sense in calling two streets. Even if you hit a top pair, you might be loosing. On the flop I think it is ok to call the bet, since it is not that big. I've seen many players on NL2 donking a flop without face cards. They think you are raising from a different position then the button so you can only have two cards J+. I see this try of some players in every single session.
On the turn it is clear that they have at least A-high. But I don't really think the bluff two streets with A-high. It is most likely they have hit a pair or have a pocket pair or even a set. I fold the turn.
As played I would bet-fold the river to bluff his lower pairs. If he has got a set, he will raise. Betsize would be about half pot.

I would also fold OTT.

Calling the donk bet on flop is ok but we have to stop pouring money there.
We should fold turn and move on.

I would even consider folding the flop. His SB calling range is mostly pocket pairs and ocassionaly some higher suited connectors and broadways like KQ, KJ, AQ, AJ. I don't think he is donking here T9, especially not JT, so his flop donking range crushes us, imo. If we call flop, I think we can only continue calling OTT if we hit our TP.

Thank you, guys!

I know this is a basic question, but from a guy start playing is here where we loose money easy...

folding the turn is a must sometimes even folding the flop

Fold flop. You shouldn't defend 100% versus donk bet, and I can think of few worse hands to do it with on this board.

Fold turn. If you thought of the flop call as a pure float with no other prospects than bluffing (requires very specific timid opponents), then abort mission. It failed.

River: If you thought of the flop call and turn call as a pure floats with no other prospects than bluffing (requires very specific timid opponents (otherwise, why are you here?)). Bet big, and possibly overbet the pot.
